All Hazard Alert Broadcast System warning sirens will sound in communities along the North Olympic Peninsula coast at noon today.

In Jefferson County, sirens are at three sites in Port Townsend — the Port Townsend marina, Point Hudson and Fort Worden — and on the Hoh reservation on the West End.

In Clallam County, sirens are at Diamond Point, Dungeness Fire Station, Four Seasons Ranch, Marine Drive in Port Angeles, Lower Elwha Klallam Community Center, Clallam Bay, the Quileute A-Ka-Lat Community Center in LaPush and at two sites in Neah Bay.

Winchester chimes will sound for 10 seconds, followed by a recording saying the alert was only a test.

A similar notification test can be heard inside buildings on National Oceanic and Atmospheric Administration, or NOAA, AHAB radios throughout Clallam County at noon Wednesday.

This will be a voice-only test of the NOAA alert system.

In an actual emergency, those indoors should check for messages from the Emergency Broadcast System on their radios or televisions if possible.

Sound tests are to verify the system's capabilities to send a timely warning notification to the coastal communities of Clallam, Jefferson, Pacific and Grays Harbor counties.

The Jefferson County Department of Emergency Management urges citizens to purchase a NOAA weather radio for use in emergencies.

The department will program the radio for free.

For more information, phone the department at 360-385-9368.

Clallam County would like residents who hear the test to call in information regarding the sirens, the voice announcement and where they were when they heard the test siren.

Phone 360-417-2525 today or Tuesday to leave information.

Clallam County Emergency Management has trainers in tsunami preparedness available for free to service agencies and schools.
